Proposed Charter for the 
Configuration Description, Deployment, and Lifecycle Management (CDDLM) 
Working Group

Administrative

Definition

The Configuration Description, Deployment, and Lifecycle Management (CDDLM) Working Group (WG) will focus on three main topics: a) configuration description of Grid Services; b) deployment of Grid Services on Grid infrastructure; and c) lifecycle management of deployed Grid Services (including failure detection and redeployment if necessary). Legacy applications (not Grid Service-based) are included in our scope and we will address their needs using wrappers.

Charter

Focus/Purpose

 

Deploying any complex, distributed service presents many challenges related to service configuration and management. These range from how to describe the precise, desired configuration of the service, to how we automatically and repeatably deploy, manage and then remove the service. Description challenges include how to represent the full range of service and resource elements, how to support service "templates", service composition, correctness checking, and so on. Deployment challenges include automation, correct sequencing of operations across distributed resources, service lifecycle management, clean service removal, security, and so on. Addressing these challenges is highly relevant to Grid computing at a number of levels, including configuring and deploying individual Grid Services, as well as composite systems made up of many co-operating Grid Services.

 

Hence, the proposed WG (CDDLM) will address how to: describe configuration of services; deploy them on the Grid; and manage their deployment lifecycle (instantiate, initiate, start, stop, restart, etc.). The intent of the WG is to gather researchers, developers, practitioners, and theoreticians in the areas of services and application configuration, deployment, and deployment life-cycle management and to explore the community need for a broader effort in this area.

Scope

 

There are many proprietary and open source systems that partially overlap CDDLM, but there is no consistent and standardized system or method which interoperates across various platforms, languages, and services/applications in a secure and reliable way. As examples, an ideal CDDLM would enable: unified definitions of configuration parameters to replace or mask the many different configuration notations and access mechanisms in use today (e.g. XML, ini files, SQL); methods for validation of configurations at definition- and run-time; system composition from sub-systems; separation of concerns of functionality and configuration; auto-discovery, self-monitoring, etc.

 

Within group there exists extensive experience gained with one such system, called Smart Framework for Object Groups (SmartFrog). The intent to release SmartFrog as open source was announced at GGF8. It is a good starting point to create the specifications which cover applications to other systems, platforms, and languages. See www.smartfrog.org for more details.

Goals and Milestones

This group is chartered with the creation of the CDDLM specifications and it encourages companies and individuals to develop at least two reference implementations. We hope to accomplish the following specifications:

1. Configuration Description Language Specification

2. Intermediate Configuration Description Language Specification
(Configuration expressed in 1. with inheritance, dependencies, and variables resolved)

3. Basic Services Specification

4. Component Model Specification (component representation and implementation)

We hope to accomplish the following milestones:

·   March 2004, GGF10:     

1.       CDDLM WG fully formed and core charter members established;

2.       Completion of draft versions of the documents 1 & 2 above.

·   June 2004, GGF11:       

1.       Final drafts of documents 1 & 2;

2.       First drafts of documents 3 & 4

·   October 2004, GGF12:  

1.       Final drafts of documents 3 & 4;

2.       preliminary reference implementations

·   March 2005, GGF13:     

1.       Two interoperable reference implementations complete

To be applied to the following domains

·   Web & Grid Services

·   Applications for utility computing

·   Large scale distributed computing

Potential Relationship to other Working/Research Groups

·   CMM and OASIS Web Services Distributed Management (WSDM) TC

·   GRAAP WG (WS Agreement)

·   Newly proposed BoF on “Grid Business Processes”

·   OGSA WG

·   Data Center Markup Language (DCML)

Management Issues

 

Evidence of commitments to carry out WG tasks

 

Dejan Milojicic has an exclusive assignment in his company to work on the CDDLM; he has a strong management and leadership experience. He and his group plan to attend all GGF meetings during the CDDLM life span and also to hold interim working sessions (at least three times a year or on as-needed basis).

 

Takashi Kojo is one of the earliest members of the architecture design of the Business Grid Project which is joint development effort of Japanese top IT venders of NEC, Fujitsu and Hitachi along with National Institute of Advanced Industry, Science and Technology. Takashi Kojo is committed to participate in all GGF meetings and regular CDDLM-WG phone conferences, to lead the CDDLM, and to make technical contributions.

 

Pre-existing Documents

 

There are existing documents available on the topic of SmartFrog, a system that motivated proposal for this working group. The documents are available off of www.smartfrog.org. The open source implementation and extensive additional documentation will be shortly available from the same location.

 

Exit Strategy

 

This working group is intended to have a short life-span because there is already an existing system as a proof point. We hope to use this extensive experience in order to come up with a Grid-specific specification and a couple of reference implementations. We believe that we can achieve this in as early as 18 months, but not longer than 24 months. Our milestone is to have two reference implementations based on the adopted specification.

Charter Members

Two dozen people (of approximately three dozen present at the BoF) expressed their interest in working in the CDDLM-WG, and almost a dozen of those are prepared to work very closely and contribute to the CDDLM-WG. In particular, we have William Lee (Lesc, UK); Stuart Schaeffer (Softricity, US); Fred Maciel (Hitachi, Japan); Takashi Kojo (NEC, Japan); Hiro Kishimoto (Fujitsu, Japan); Inder Monga (Nortel Canada); Patrick Goldsack, Dejan Milojicic, and Peter Toft (HPL, UK & US); and Ian Taylor (Cardiff Univ., UK). Therefore, we have representatives from three continents, four countries, and two academic and six industrial institutions.

 

We have commitments from five companies to pursue three reference implementations of the CDDLM specifications: the BizGrid project (Fujitsu, NEC, and Hitachi), Softricity, and HP.

 

In addition, we have spoken to a number of industrial and academic organizations which expressed interest in the topics addressed by CDDLM and which are considering joining this effort. We approached Oracle, BEA, JBOSS, CERN, UCSD, Berkeley, and Stanford. We also plan to approach a number of other organizations, such as IBM, Microsoft, SAP, Siebel, Sun, Cisco, Philips, NASA, Caltech, Pittsburgh SC, etc.
